FIRE-HOSE NOZZLE.

A SPECIFICATION forming part of Letters Patent No. 692,571, datedFebruary 4, 1902.

Application filed July Z0, 1901. Serial No. 69,119. (No model.)

To @ZZ wiz/0711, it may concern:

Be it known that I, FRED W.WIEMAN,a citizen of the United States,residing at Lawrence, in the county of Douglas and State of Kansas, have invented new and useful Improvements in Fire-Hose Nozzles, of which the following is a specification. l

This invention relates to nozzles, being especially designed with reference to the needs of firemen, the object of' the invention being to provide a nozzle of such construction as to admit of ready and quick adjustment, whereby a fireman may direct the entire iiow of water in a single stream of variable size or in connection with the main stream throw into operation an annular spray, the nozzle also having provision whereby such annular spray may be directed forward toward the fire or laterally, so as to form a lire-shield between the conliagration and the fireman, or backward, so as to keep the clothing and face and hands of the fireman saturated with water, thereby protecting such fireman from the injurious eects of the intense heat, flame, and iirebrands.

The parts whereby the various adjustments are effected are conveniently arranged, so as to be under the immediate control of the fireman, and the several adjustments maybe effected entirely without the use of wrenches, tools, or other implements.

With the above and other objects in View, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination, and arrangement of parts hereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a lire-hose nozzle embodying the present invention. Fig. 2 is a central longitudinal section through the same. Fig. 3 is a sectional view of the outer 'nozzle-tube. Fig. 4 is a diametrical section through the head forming the deflecting agent. Fig. 5 is a similar view taken through the conical hood. Fig. 6 is a central section taken through the valve-seat. Fig. 7 is a central longitudinal section through the casing or body of the nozzle. j Fig. S is a detail section showing the connections between the valve stem and valve -operating handle. Figs. 9, 10, and 11 are detail fragmentary sections illustrating different adj ustmeuts ofthe conical hood for directing the annular spray forward, laterally, and backward.

Like numerals of reference designate like parts in all the views.

The nozzle contemplated in this invention comprises, essentially, a tubular bod y or casing 1, which may be of any desired diameter, the same being. usually of approximately the size of the ordinary iire-hose in common use at the 'present time. Anysuitable provision may be made for coupling the nozzle to tho hose.

- In carrying out the present invention I employ a center tube 2, which constitutesv the main stream-pipe of the nozzle, said pipe be ing arranged centrally Within the nozzle and extending throughout the greater part of the length thereof. pipe 2 is exterior-ly threaded, as at 3, and screwed into an internally-threaded socket formed in the adjacent' end of the valve-casing 4, which is arranged in the inner portion of the casing 1 and provided with a tapered valve-seat 5, in which is rotatably mounted a plug-valve 6, the means for operating which willbehereinafterdeseribed. Thevalve-seat is provided at its outer end with a disk-shaped head 7, the outer portion orperiphery of which constitutes a rim 8, which is brought to bear and permanently seated against an internal annular shoulder 9 within the casing 1. The head '7 is also provided with a radial series of ports or openings 10, so as to admit water to the annular space intervening between the outer surface of the stream-pipe 2 and the in-V ner wall of the outer casing or body'l of the nozzle. v

The stream-pipe 2 at a point intermediate its end is exteriorly screw-threaded, as at 11, to receive a head 12, which is screwed thereon, as clearly illustrated in Fig. 2, and provided with ports or passage-Ways 13, permitting the escape of the water, such passage-ways or ports 13 being arranged in an annular series corresponding with the similar ports 10 in the valve-casing. The outer portion of the head 12 is internally recessed, as at 14, and provided with` an annular shoulder 15, against which is seated the inner end or head 16 of what I term the outer nozzle-tube 1'7, which surrounds the out-er extremity ofthe stream- The inner end of the stream` IOO pipe 2, leaving an annular space 1S, through which the water finds its exit.

The head or inner end of the outer nozzletube 17 is provided with a circular series of ports 19, adapted to register with the ports or passage-ways 13 in the head 12, and said parts are so mounted as to admit of a sufficient amount of relative rotative movement to bring the ports 13 and 19 into and out of alinement with each other for the purpose of cutting off the stream which passes through the space 18 or giving exit to such stream, which thereby combines with the stream passing outward through the center pipe 2 and forms a large stream well adapted for use when the fire is close at hand.

The head 1G is provided with a central opening, through which the stream-pipe 2 passes, and the pipe 2 is provided exteriorly with an annular shoulder 20, which bears against the head 16 and holds the outer nozzle-tube 17 firmly in place, while admitting of the necessary amount of'l rotative `movement thereof to bring the ports 10 into and out of register with the passage-ways 13 in the head 12. The head `12 is further provided with an annulargroove orseat 21 for the reception of the inner annular fiange 22 of a conical head The head 23 comprises an exteriorly milled or corrugated sleeve 24, having a screw-threaded engagement, as at 25, with the casing 1, whereby by rotating said sleeve the latter may be adjusted back and forth on the casing 1 for a purpose which will hereinafter appeal'. Extending outward from the sleeve 24 are the concentric annular fianges 22 and 2G, the flange 22,- as previously stated, being received in the annular seat or groove 21 in the head 12, while the outer fiange 2o' extends around the inclined outer wall or periphery 27 of the head 12, as clearly illustrated in Fig. 2. The flange 26 of the conical hood serves to cut off the spray when adjusted into close relation to the head 12, as illuetrated in Fig. 2, and when movcd away from the head it acts as a deflector for causing the water passing between it and the head to escape in an annular spray in a forward direction or away from the fireman. The inner portion of the head is recesssed to form an annular gutter 2S, having a backwardly-extending annular lip or edge 29, which when the hood has been moved backward to its full extent serves to direct an annular spray backward for the purpose of saturating the clothes of the fireman and protecting him from the injurious effects of the fire. The backward or inward adjustment of the hood is limited by means of an annular shoulder 30, formed on the outside of the casing 1, against which the inner end 31 of the sleeve 24 is adapted to abut.

The flange 22 is provided with side ports 32, through which the water may escape into the gutter 2S and space within the flange 2G.

NVhen the hood is adjusted inward to the full extent, as shown in Fig. 11, the outer rim portion 33 of the flange 22 is withdrawn far enough to allow the water to pass over it as it flows outward through other ports or side openings 34 in the head 12. The head 12 is further provided with a rabbet 35 to receive the outer end of the shell or casing 1, as illustrated in Fig. 2.

The plug-valve 6 is provided with the usual opening or passage-way 3G and has connected therewith oppositely-ezteuding stems 37 in line with the axis of movement of the plug and extending outward through openings 38 in the casing 1. Each ofthe stems is provided with an enlargement or collar 39, which is received in a corresponding recess 40, formed in an outward eztension 41 of the casing, as clearly illustrated in Fig. 8. The outer portion 42 of each stem is enlarged and provided with a transverse opening or socket 43 for the reception of one of the extremities of a bail-shaped valve-operating handle 44, (illustrated in Fig. 1,) held in place within the opening 43 by means of aset-screw 45. The portion 42 of the stem is surrounded by a ball 4G, and a packing-washer 47 is interposed between the ball/1G and the casing 1, so as to form a water-tight joint and provide the necessary frictional resistance for holding the valve in its adjusted position after it has been operated by the handle 44.

By means ol' the valve 5 water may be admitted to or shut off from the center tube or stream-pipe 2, and by means ofthe outer nozrletube 17 the water may be cut off from or admitted to the annular space between the stream-pipe and casing 1. In this way a single central stream of great velocity may be obtained, oralargeannularstream, orboth com. bined. By moving the conical hood 23 inward a short distance, as illustrated in Fig. 9, an annular stream or spray of widely-diverging arca may be directed through the space between the outer flange 26 of the hood and the periphery 27 of the head, the direction of the annular stream being illustrated by the arrows in Fig. 9. By adjusting the hood still farther inward to the position illustrated in Fig. 10 the annular spray is directed straight outward laterally or in a radial direction, as indicated by the arrow in said figure.

By moving the hood inward to its limit, as illustrated in Fig. 11, the water enters the gutter in the inner side of the head and is thereby diverted or defiected and caused to spray rearward, as indicated by the arrows in said figure, thus saturating the clothes of the fireman for the purpose previously stated.

It will thus be seen that various adjustments may be obtained and'streams or sprays of various forms and characters obtained. Further, all of the adjustments necessary to obtain the said streams or sprays can be effected readily and quickly by the fireman without resort to wrenches or other tools. The invention is susceptible of various changes in the form, proportion, and the minor details of' construction, which may accordingly be reI IOO sorted to without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-
